Copyright law is complicated. While I feel comfortable with the copyright status of all vintage images on the website I can not officially grant you permission to use those images. If it is one of my personal photographs you may request permission.
If you need images for a publication I suggest you buy a vintage photograph on Etsy or eBay, or purchase a stock image with a clear copyright status.
Students/non-profits usually can reuse images in papers or school projects without copyright infringement.
